MOTOR-VEHICLE.

SPECIFICATION forming part of Letters Patent No. 712,546, dated November 4, 1902.

Application filed May 31, 1902. Serial No. 109,673. (No model.)

field, in the county of Clark and State of Ohio,

have invented certain new'and useful Improvements in Motor-Vehicles, of which the following is a specification.

My invention relates to self-propelling vehicles, and more especially relates to steam carriages or drays, although other motive power may be employed.

The object of myinvention is to provide a simple, strong, and efficient construction for carrying heavy loadsyso arranged as to compensate for the jars and strainsincideut to travel over uneven roads. A

A further object of my invention is to so combine and arrange the parts that the platform of the carrying-body shall be at the top of the frame structure and the self-propelling devices underneath the platform, thus giving free and easy access to the platform of the carrying-body.

My invention consists of the constructions and combinations hereinafter described, and set forth in the claims.

In the accompanying drawings, Figure l is a side view of a steam-drayembodying myinvention. Fig. 2 is an end view of the front wheels and frame, partly broken away to show the carrying-spring, also the arrangement of the steering apparatus. Fig. 3 is a horizontal section of: said wheels and frame, with a plan view, partly in section, of said steeringapparatus. Fig. dis a horizontal section of the rear wheels and frame, with a plan View of the motor, its carrying-frame, and driving connections. Fig. 5 shows the platform-supports. Fig. 6 isa detail of same, and Fig. 7 shows pivoted connection of motor-carrying frame to platform.

Like parts are represented by similar let-' ters of reference in the several views.

In the drawings, arepresents the carrying wheels, preferably formed with staggered spokes and having the hubs in the rear wheels inwardly'extended, so as to carry the spurgears hereinafter mentioned. Spindles for the frontwheels are preferably formed with the laterally and oppositely extending arms a, pivoted at o to the axle (1 the ends a of said levers being pivoted together by the .not'being shown.

cross-bar a and the opposite ends being connected by a flexible rope a turned around the drum (1 and fastened to said drum at a the tension of said rope being adjusted by a screw-threaded connection a. The drum a and the worm-gear c are rigidly attached to the shaft a l and are operated by the handwheel a through the shafts (L13 and on and the gears 0. the worm for said worm-gear The rope c is preferably of a flexible or pliable material, so as to be somewhat elastic, which will give easier control to the steering apparatus.

The body-carrying supports are preferably cast in one piece, and to make them as light as consistent with the required strength I preferably cast them of malleable iron or steel, having the ends parts I), joined by the connectingwebs Z9, and I further lighten them by forming the end parts with the centrally-extending webs?) and the laterally-extending ribs 12 to strengthem them. The end parts b have the slots 19 and the bridge b at the top of same. i

I provide the blocks b with the recess 1) to rest over the axle and the laterally-extending pins 19 to travel in grooves 19 formed in the supports at the side of the slots to guide the blocks in said slots. I preferably form the tops of these blocks rounding, upon which the correspondingly-r0unded bottom of the spindle-base Z2 is adapted to rest, said base having the lateral projections b adapted to travel in the groove b of said supports. The spindle Z7 is rigidly attached to or formed integrally with said base and extends through a perforation in the bridge b and a carryingspring I), through which the spindle projects, extends between the base Z9 and the bridge 12 of the support.

It will be seen that the arrangement is such as to give a loose but strong construction adapted to compensatefor the various strains incident to travel over uneven roads or obstructions, the rounded connection between the block and base especially taking care of the variation in vertical movement of the respective sides of the machine.

On the supports I mount the carrying body or platform,in the construction of which I preferably employ the longitudinal steel channels c, with wooden beams a secured between IOO them, forming stringers, to which the supports are secured, and the frame is further strengthened by the cross-pieces c as well as by the floor, which is nailed, bolted, or otherwise secured to the wooden beams of th stringers.

1 preferably form the motor-carrying frame (1 in a single casting adapted to also carry a counter-shaft and driving-gears, although said motor may be directly connected, the crank-shaft of the motor taking the place of the counter-shaft. One side of said frame I pivot to the rear axle d by the journals d and the opposite side is preferably carried by the pin d pivoted in the hanging frame (1, which is pivoted at d to the body or platform. I securely bolt or otherwise secure the motor e to the frame d, and on its crank-shaftI have shown two spur-pinions e of different diameters, adapted to mesh with spur-gears e of correspondingly different diameters, formed on the periphery of a drum 6 of a differential or compensating gear, said pinions being splined to said shafts, so that either one may be thrown into gear to givedifferent speeds. I journal the counter-shaft e at one end in the brass box e and at the other end it carries a sleeve journaled in the box a the bevel-gear 6 being attached to said shaft and the bevel-gear a to said sleeve, the pinion e meshing with said gears, being pivoted to the inner periphery of the drum e the arrangement being such as to drive the rear wheels independently of each other, the power being transmitted to the wheels through the pinions 6 one on said shaft and the other on said sleeve, said pinions mesh- 'ing with the gears 6, attached to the hubs of the wheels, as shown.

It will be seen that the motorcarrying frame, being pivoted to the rear axle, always maintains its alinement parallel with said axle and keeps the driving-pinions in proper mesh with the gears on the carrying and driving wheel under the vibration caused by uneven roads or the passing of the machine over obstructions. Furthermore, by pivoting the opposite side of the frame at its transverse center the vertical movement caused by passing over obstructions on either side of the machine is compensated for.

1 preferably secure the supply-tankf and the boilerf to the under side of the bodyplatform, and the supply f to the engine is flexibly connected to the boiler to compensate for the varying move'mentbetween the body and the motor-carrying frame, and the exhaust may be flexibly connected to the body in like manner. At the rear of the body I securely attach to the under side of the platform the water-tankf which I also preferably secure to the end parts I) of the bodysupports, which will more firmly hold the tank and further strengthen the body-carrying platform.

Upon each side of the water-tank I pivot the brake g to bear against the rear Wheels,

pressure being applied by a single-acting piston and its rod g, pivoted at g to said brake. Steam or air may be used to drive the piston, the supply and exhaust to the cylinder being furnished by a three-way valve in a well-known manner or in any other suitable way, the brake being released and the piston returned by the tension-spring g Having thus described my invention, I claiml. The combination with a carrying-platform and the axles of a vehicle, of supports for said platform consisting of transverse frames having slotted ends therein, two-part bearing-blocks, the lower part adapted to engage said axle and rounded on top to receive the correspondingly-munded bottom of the upper part, said blocks being adapted to fit and move in said slots, carrying-springsin said slots engaging said frames and carried by said bearing-blocks,substantially as specified.
